Print Managing Server, Print Managing Method, Program, and Recording Medium

1. A print managing server which is connected to a plurality of printers through a network and stores print data for printing by the plurality of printers in combination with user information, comprising: a receiving unit configured to receive, after an authenticating process, a first command including first user information on a first user from a first printer of the plurality of printers; a determining unit configured to determine whether the first user has logged-in to a second printer of the plurality of printers; a control unit configured to control in such a manner that, if the determining unit determines that the first user has logged-in to the second printer, a second printing process, corresponding to the first user information included in the received first command, for execution for the second printer is canceled and a first printing process corresponding to the first user information included in the received first command is executed for the first printer so that a printing process based on print data which has been processed for the second printer is not executed again.

2. A print managing server according to claim 1 , wherein the authenticating process is an authenticating process based on identification information stored in a storage medium read out by a storage medium reading unit provided for the first printer.

3. A print managing server according to claim 1 , wherein the control unit allows a storing unit to store printer information of the second printer which is executing the second printing process and second user information included in a second command which has requested the second printing process in association with each other, and when the second printing process which is being executed is stopped for the second printer according to the reception of the first command including the first user information from the first printer, the control unit changes the second user information stored in the storing unit in association with the second printer to the first user information included in the first command received from the first printer.

4. A print managing server according to claim 1 , wherein the first command including the first user information includes a command for requesting a list of the print data stored in combination with the first user information.

5. A print managing server according to claim 4 , wherein the first command including the first user information includes a command for requesting the printing of the print data selected from the list of the print data obtained based on the command for requesting the list of the print data.

6. A print managing server according to claim 1 , wherein the first command including the first user information includes a command for requesting the printing of all of the print data stored in combination with the first user information.

7. A print managing server according to claim 4 , further comprising a holding unit configured to hold display unit construction information of each of the printers, and wherein when the command for requesting the list is received, based on the display unit construction information of the printers held in the holding unit, the control unit controls whether the list of the print data is transmitted or all of the print data stored in combination with the first user information included in the command is transmitted to the printer of a transmitting source of the first command.

8. A control method of a print managing server which is connected to a plurality of printers through a network and stores print data for printing by the plurality of printers in combination with user information, comprising: a receiving step of receiving, after an authenticating process, a first command including first user information on a first user from a first printer of the plurality of printers; a determining step of determining whether the first user has logged-in to a second printer of the plurality of printers; a command control step of controlling in such a manner that, if the determining step determines that the first user has logged-in to the second printer, a second printing process, corresponding to the first user information included in the received first command, for execution for the second printer is canceled and a first printing process corresponding to the first user information included in the received first command is executed for the first printer so that a printing process based on print data which has been processed for the second printer is not executed again.

9. A non-transitory computer-readable storage medium which stores a control program for causing a computer to execute a control method according to claim 8 .
